Advice Needed – Should I Get a BlackBerry Pearl?

I’ve decided that after over 6 years with Vodafone, it’s time to leave.

I haven’t really been paying attention to the price plans from other networks as the price plan that I had from Vodafone worked fine for me – 350 mins and a £60 allowance for data and SMSs which worked out to 500 texts or 20MB. But since I got my Dell X51V, I’ve been using my N80 more and more as a modem and my data usage has shot up. The problem though isn’t the extra cash I’m spending, it’s more that because my cap is so ‘low’ rather than staying connected all day, I’m rationing my own usage to stay within my tariff.

I hate this, and my friend ‘Dollarman’ pointed out to me in the week that T-Mobile’s web ‘n’ walk Plus tariffs give unlimited data, as well as more minutes and texts, free usage of T-mobile hotspots and 300 wi-fi minutes a month with BT Openzone hotspots for less money!
I can’t believe I’ve been so out of touch and I’m switching ASAP. The only ‘problem’ I have is that the only phone they have that I like which has a built-in modem I can use with my Dell X51V, is the BlackBerry Pearl. I’m very anti ‘CrackBerry’ and I’ve seen how they can become like a drug to some people. Ive always been worried that I’ll become one of these people, as I like to leave my work behind me when I leave the office. So, I’m in two minds about getting one.

Is the BlackBerry Pearl a GOOD phone? I know it’s a good email device, but does anyone have experiences of using one as a phone? How does it compare to say a Nokia or a Sony Ericsson?
